To all whom it may concern:

Be it known that I ALBERT STEFFIN, of New Bedford, in the county of Bristol and State of Massachusetts, have made certain new and useful Improvements in Glass Shades; and I do hereby declare the following to -be a full and clear specification thereof.

The present invention relates generally to glass shades, and has more particularly reference to a new article of manufacture and the method of producing the same.

The object of the invention is to produce a shade for electric and other lights, which is capable of being brilliantly ornamented -Without having that glaring effect upon the eye which is so objectionable in shades of this class. l

To this end the inyention embodies the following: The top surface of the shade is preferably uninterrupted, though notnecessarily imperforate, and is blown or molded so that such surface comprises raised ornamental figures, after which the exterior surface is acid- .ized or frosted to vmake it translucent, whereby the light is properly diffused and sufiiciently subdued, so

on its interior surface in the appropriate colors of the raised ornamental figures. l i

The ornamental figures may of course take any form desired, but preferably I use representations of flowers or fruit, whose natural colors applied to the interior surface are beautiful and therefore leud themselves readily to the formation of striking designs, such as a bouquet of flowers. A The article thus produced 'is very ornate inappearance when a light is placed inside,.the frosted exterior surface subduing the light while the brilliant colors .on the interior surface of the shade produce'a very beautiful effect which is greatly heightened by the play of light through the ornamental design blown in the body of the shade-itself. V

The invention is particularly Well adapted to be used' with electric lights where it is possible to `have an uninterrupted top surface, no central aperture being necessary for the escape of the gases of combustion. With this construction the design is not spoiled by light escaping through any large central aperturaand an un- I broken effect cantherefore be produced. "It will be understood that I do not wish 'to limit myself to a shade whose top Vsurface isnecessarily imperforate.

`In the accompanying drawingsl have shown my ln- Aventonapphed in a concrete form for use with the slectric light in which designs of flowers are blown into the body of the shade, but it will of course be understood that the lshade may be formed with any ornamental y 'view taken on line 2-2 of Fig. l. Fig. 3. is a side elevation of a shade showing also the support used for the same.

Similar characters of reference indicate corresponding parts in the different views.

A. indicates the body of the shade which is blown with ornamental figures a, representing in the present instance, a bouquet of` flowers. The exterior surface of the shade is indicated at b, and this surface is frosted or acidized so as to make the shade translucent when an interior light shines through it. c indicates the inner surface of the shade which is decorated in colors of the molded ornamental figures.

The shade a is open underneath and may be suitably supported byits base or rim resting on a circular bracket b or some other means of support on which the rim will rest.

In that step of the process which comprises the blowing and molding of the shade I thicken the glass at various points of the ornamental design so that portions of the glass project considerably beyond the surface. This molding of figures in glass of a dome shaped shade with an open base for the introduction of a lamp produces a striking effect which has not been obtained so far as I know in any previous instance. Where the shade has an uninterruptedly closed top surface and the ornamentall figures blown in the glass are painted on the interior of the irregularly blown surface the effect is heightened. The thickening of the glass at certain points of the ornamental figures of the shade causes a prismatic effect and this effect is heightened by the application of the appropriate colors of the iiowers on vthe irregular interior surface thereof. This thickening of the glass is indicated at d Fig. 2.

What is claimed is:

1. As a new article of manufacture, a glass shade with molded ornamental figures, the exQterior surface of which is frosted, und the interior surface colored to correspond to the ornamental figures.

2. A dome shaped glass shade comprised of molded figures 'with the glass forming such molded figures thicker nt lome parts than at others, the exterior surface of which ls frosted nud the in terfor surface colored to correspond to the natural colors of -the ornamental figures;

i-l. As n new artlcleof manufacture, a glnsslshade comprlslng a dome having un uninterrupted top surface 4with ornamental figures blown therein, a frosted exterior sun fece, and a colored interior surface.
